ALVIN C. KINGSBURY, OF DEOORAH, IOWA.

BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 436,422, datedSeptember 16, 1890.

Application filed April 17,1890. Serial No. 348,284. (No model.)

To all whom it may concern:

Be it known that I, ALVIN O. KINGSBURY, of Decorah,in the county ofWinneshiek and State of Iowa, have invented certain new and usefulImprovements in Butter-VVorkers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in butter-workers.

Hitherto machines of this character have been arranged with a rotarytable pitching toward the center for the discharge of the brine andbuttermilk at that point as fast as worked from the butter; also, therollers for operating on the butter have been previously set and couldonly be changed at the expense of a great deal of time andinconvenience.

The object of my invention is to provide improved means for the supportof the table, to provide for the raising andlowering of the rollersinstantly while the machine is in motion, and to increase the facilitiesfor drawing the brine and buttermilk from the butter; and with theseobjects in view my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improvedbutter-worker. Fig. 2 is an end elevation, and Fig. 3 is a verticalsection.

A represents the frame upon which the various parts of the machine aresupported, the same being mounted on suitable legs 1 1. A vertical shaft2 is journaled in this frame, and

this shaft carries a circular table 3, upon which the butter is Worked.This table is pitched downward from the circular ridge 4 both toward thecenter and the outer edge of the table to facilitate the draining of thebrine and buttermilk from the butter, which by this means drips from thecenter and outer edge, thus hastening the process to a very considerableextent.

A pair of cone-shaped rollers '5 5 are arranged to operate on the buttercarried by the table. These rollers are dished about mid way of theirlength to conform to the shape of the ridged surface of the table, andthey both extend radially across the table, the smaller ends toward thevertical shaft. The rollers are journaled in the arms 6 6 and 7 7 of thevertically-moving frame 8, and the frame is loosely mounted at itsopposite ends on the vertical post or upright 9 off at one side of theframe and on the upper end of the vertical shaft 2, so that verticalmovement may be imparted to it at pleasure in order to raise or lowerthe rollers 5 5.

To operate the movable frame, a hand-lever 10, fulcrumed, preferably, onthe hinged or pivoted arm 11, is pivotally connected with the pintles 1212 of the movable frame and adapted to be swung in either direction, asthe case may be. To look the lever, it is provided with a pawl orsimilar device for engaging teeth on the upright or frame A. The objectof this construction is to admit of prompt action in raising andlowering the rollers without the necessity of stopping the machine. 7

The table is rotated by means of a horizontal shaft 13,1'evolublysupported beneath the table, and this shaft is furnished on its innerend with a bevel gear-wheel 14, the teeth of which are meshed withasimilar but larger bevel gear-wheel 15 on the vertical shaft, wherebythe motionof one shaft is communicated to the other. A loose and fixedpulley 16 is mounted on the outer end of the horizontal shaft, and theyare driven by a suitable belt (not shown) for the purpose.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to limitmyself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a butter-Worker, the combination, with a suitable support, of arotary table, the latter having a circular ridge on its upper surfaceand sloped or pitched toward its center and periphery, and rollers madeto conform to the shape of this table and adapted to operate thereon,substantially as set forth.

2. The combination, with a support, a 1'0 tary shaft, and a tablecarried by said shaft,

of a, roller-frameloosely mounted on theframe specification in thepresence of two subscriband on the upper end of the rotary shaft,rolling witnesses.

ers journaled at their opposite ends in said frame, a hand-lever forelevating the frame, ALVIN KINGSBURY' 5 and means for looking it in anydesired ele- Witnesses:
